What are the stages of a longhorn beetle life and how long do they live?

I can’t speak about all longhorn beetles, but the more famous wood boring kind (like the one in the picture above, which is a pine sawyer) start out as an egg in the tree. The adult female chews a hole in the tree and then turns around and deposits the eggs inside. The eggs hatches and the larva develops through several instars (a stage in between molts). Then the larva goes into a pupal stage and eventually reaches adulthood and chews its way out of the tree.

How long they live for depends on a lot of things…like food source, predation, in the wild vs. the lab, which species. I would say as generally speaking that they could live for several weeks.
